Biological indicators of stress in pacu (Piaractus mesopotamicus) after capture.
The effects of capture (chasing, netting and air exposure) on cortisol, glucose, chloride, sodium, potassium and calcium concentrations, osmolality, hematocrit, hemoglobin concentration, red blood cells count (RBC) and mean corpuscular volume (MCV) were investigated in pacu (Piaractus mesopotamicus). A total of 132 fish (49.7 +/- 11.7 g) were subjected to capture and 3 minutes air exposure and ...
متن کاملThe effect of hypoxia and recuperation on carbohydrate metabolism in pacu (Piaractus mesopotamicus).
A study of the hematological parameters, glycogen, glucose, and lactate, and the activity of malate and lactate dehydrogenases was carried out in blood and tissues of fishes submitted to two, four, and six hours of hypoxia and recuperation. Only after 4 h of hypoxia was there a drop in liver glucose. Alter 16 h, a drop in lactate and a rise in glucose in practically all tissues signaled a recup...
متن کاملHemolytic activity of alternative complement pathway as an indicator of innate immunity in pacu (Piaractus mesopotamicus)
The objective of this study was to evaluate the methodology to establish the hemolytic activity of alternative complement pathway as an indicator of the innate immunity in Brazilian fish pacu (Piaractus mesopotamicus), in addition to verifying the influence of β-glucan as an immunostimulant. Fish were fed with diets containing 0, 0.1 and 1% β-glucan, during seven days, and then inoculated with ...
متن کاملQuality parameters of pacu (Piaractus mesopotamicus) and tambaqui (Colossoma macropomum) gutted and stored on ice for different periods
The purpose of this work was to assess the quality of pacu (Piaractus mesopotamicus) and tambaqui (Colossoma macropomum) gutted and stored on ice for a period of 19 days. Color, texture, pH, acid value, peroxide value, thiobarbituric acid reactive substances, total volatile bases and counts of aerobic mesophilic heterotrophic and psychrotrophic bacteria assessments were performed in the meat of...
متن کاملLeukocytes respiratory burst activity as indicator of innate immunity of pacu Piaractus mesopotamicus.
The present study evaluated the assay to quantify the respiratory burst activity of blood leukocytes of pacu as an indicator of the innate immune system, using the reduction of nitroblue tetrazolium (NBT) to formazan as a measure of the production of reactive oxygen species (ROS). In order to assess the accuracy of the assay, fish were challenged by Aeromonas hydrophila and sampled one week aft...
